The minutes from the June meeting were read and approved as was the Treasurer's report. Committee reports followed. Guidescope editor Bill Ruth reported that the newsletter was status quo with some submissions coming in which are appreciated. The Website is operating as intended with no issues. Under Instrumentation, John Reising will repair the 2 diagonal from the 4 Unitron refractor. The Unitron is being used in place of the orange tube C-14 which is currently at Celestron for cleaning. With five major planets currently visible and Mars at opposition, we decided a refractor was the perfect instrument to use. Once the new storage building is finished, the refractor can be kept on its Unitron mount and easily carried out to one of the pads for use, which we are pleased about. It has been mothballed for too long. We currently have it mounted on a club-owned Celestron CG5 mount, but that needs to be polar aligned better and we need to find the correct power supply for it. The 2 diagonal mirror is in bad shape with the silvering deteriorated, so John will replace that mirror with one he has as a spare. The new 16 Newtonian was discussed at some length. All the components are there, but the telescope needs to be assembled and collimated. It was decided to organize the work, but to wait until the storage building is completed, and then assemble the scope on site rather than trying to move the assembled scope. With help, John can put the scope into operation in a day or so, and several Directors volunteered to help. We are hoping to have the 10 X16' storage building built by late fall. The Board also authorized Schauer to purchase two Telrad finders and one 4 extension base, one to be used on the Unitron and the other to replace a nonworking Telrad on the 12 Dob. We will probably need to purchase a third Telrad once the 16 is in operation. The OTAA committee chair reminded Directors that the MVAS OTAA is Saturday August 11 th with registration starting at 5:00 p.m. and dinner

3 sometime after 6:00 p.m. The folks at MVAS are most welcoming, and it is hoped many BRAS members attend. The Metro Parks Liaison reported that Paul Rhuby of the LCMP is being kept in the loop about the C-14 repairs by Schauer and will authorize the repair once we have an estimate (UPDATE: Celestron has given us an estimate of $ to clean, lube, collimate, ship and insure the scope, and this estimate has been passed on to the Parks for approval. Once approved, it is hoped the work would be completed in a couple of weeks.) Programing is set for the rest of the year with the exception of November which is open. Any member wishing to present a talk in November should contact any Board member or the President (BRASPres@gmail.com). The programs are as follows: August Denny Bodzash Solar Superstorms, EMP Attacks and Hardening the Grid Sept. John and Dave Planetarium show at the Oberlin College Planetarium (Peters Hall) Oct. Schauer Elections and the Annual Meeting of the Members w/ short video Nov. OPEN Dec. Annual Holiday Pot Luck Dinner at the LCMP Amherst Beaver Creek Reservation. Old Business followed with the first item being a discussion of eclipse glasses. While it is too early to order a large quantity for the next solar eclipse in 2024, it was suggested that we buy a small quantity to sell at our monthly solar observing sessions. Jeff Walsh checked several sources and found glasses available for approx. 75 cents each if we bought 100 or less. When we discovered that Greg Cox still had approx. 30 pairs, it was decided not to purchase any at this time. Elections were discussed next. Four Directors will have their terms expire: Greg Cox, Bill Ruth, Greg Zmina, and Dave Lengyel. Dave has decided not to seek reelection, so Dave's seat will be open as is the seat vacated by Lee Lumpkin last October. With two positions open, it is hoped that some members interested in helping the club will stand for election. Directors need to attend the monthly Board Meetings held on the second Thursday of each month at the Blue sky Restaurant in Amherst, and also attend and help out with as many club functions as possible. It is an opportunity to keep the club moving forward and improving, so anyone interested, please see any Board member or the President. New Business came next. The first item was a discussion of two pieces of correspondence received by the President via the address on the website. Both were from people with websites asking to have their sites linked to on our Links page. After some discussion, and after perusing both sites, it was decided not to create links to them from our site. Next came a discussion about whether to purchase additional hot food to offer at our OTAA convention. It had been suggested that places like GFS and Costco sell five pound trays of food like lasagna that we could purchase, cook in the church kitchen and serve at dinner. Jeff Walsh was kind enough to get some prices from Costco, and Schauer had a couple from GFS, but after discussion, it was decided that we had plenty of food being brought in and the additional effort and expense wasn't necessary. The final item of new business was a discussion of a date for next years BRAS OTAA convention. The best New Moon date would be Sept. 21 st or the 28 th. Schauer will coordinate with the CAA President, Bill Murman, in the hope of not selecting the same date as happened this year with

4 both our OTAAs being on September 8 th. The BRAS has used a date in September for over 30 years with CAA traditionally using a date in July. Due to scheduling conflicts the CAA has had getting their meeting facility, they moved to September last year. We moved our date last year so as not to conflict with them, but it wasn't possible to change our date this year as the Church Hall wasn't available. It is really desirable that the clubs support each other, not conflict, so if CAA isn't going to move back to July, it is hoped we can coordinate a date selection in September so we can enjoy each other's events. August dates were set, and the meeting was adjourned at 8:45 p.m. ~Steve Schauer *** How a Lunar Eclipse Changed History Last month, the world was treated to a lunar eclipse. Unfortunately for us, it was on the other side of the world. While there was no historical significance to this eclipse, such is not always the case. The lunar eclipse of March 1, 1504 literally changed the course of history. Christopher Columbus, re-discoverer (the Vikings were here first) of the New World and his crew, were in a bad way. With ships beached and supplies running short, Columbus had persuaded the natives of Jamaica to supply his men food, which they did. However, a few of Columbus' crew got greedy and were caught stealing from the natives, who then stopped the supply of food. By the end of February, the explorers were in dire straits. However, there was one last hope--a book. On one of the ships (they were grounded, not sunk) was an almanac by the astronomer Abraham Zacuto that covered the years through In the book, there were, among other things, predictions for eclipses. The ray of hope: there was set to be a lunar eclipse starting the night of February 29 and continuing past midnight into March 1. People had long been troubled by eclipses in the age before science. Pre-Enlightenment people often saw eclipses as omens, and omens of misfortune almost exclusively. In fact, this continues today even in the age of science as evidenced by the 'blood moon' prophecy concerning four consecutive total lunar eclipses of just a few years ago. Taking his fellow Europeans' fear of eclipses, Columbus made a gamble. Columbus met with the leader of the natives and warned the chief that the god of the explorers was very upset at the food supply having been cut off. As a sign, Columbus said that his god would make the Moon turn blood red. While they were probably initially skeptical, the natives' skepticism turned to fear because, just as predicted, the Moon started to disappear and then reappeared--blood red. The natives then went to Columbus, promised him food, and begged him to intercede with God on their behalf and make the Moon go back to normal. Using an hourglass to time totality, Columbus, shortly before totality ended, told the natives that God had forgiven them. Soon after, the Moon went back to normal and the rest, as they say, is history. ~Denny Bodzash
